TL;DR: On the basis of the safety, pharmacokinetics, and antitumor activity in patients with glioma, the intermittent administration of LY2157299 at 300 mg/day is safe for future clinical investigation and was safe, with no cardiac adverse events.
Abstract: Purpose: TGFβ signaling plays a key role in tumor progression, including malignant glioma. Small-molecule inhibitors such as LY2157299 monohydrate (LY2157299) block TGFβ signaling and reduce tumor progression in preclinical models. To use LY2157299 in the treatment of malignancies, we investigated its properties in a first-in-human dose (FHD) study in patients with cancer. Experimental Design: Sixty-five patients (58 with glioma) with measurable and progressive malignancies were enrolled. Oral LY2157299 was given as a split dose morning and evening on an intermittent schedule of 14 days on and 14 days off (28-day cycle). LY2157299 monotherapy was studied in dose escalation (part A) first and then evaluated in combination with standard doses of lomustine (part B). Safety was assessed using Common Terminology Criteria for Adverse Events version 3.0, echocardiography/Doppler imaging, serum troponin I, and brain natriuretic peptide (BNP) levels. Antitumor activity was assessed by RECIST and Macdonald criteria. Results: In part A, 16.6% (5/30) and in part B, 7.7% (2/26) of evaluable patients with glioma had either a complete (CR) or a partial response (PR). In both parts, 15 patients with glioma had stable disease (SD), 5 of whom had SD ≥6 cycles of treatment. Therefore, clinical benefit (CR+PR+SD ≥6 cycles) was observed in 12 of 56 patients with glioma (21.4%). LY2157299 was safe, with no cardiac adverse events. Conclusions: On the basis of the safety, pharmacokinetics, and antitumor activity in patients with glioma, the intermittent administration of LY2157299 at 300 mg/day is safe for future clinical investigation.

TL;DR: The authors hypothesized that inhibition of VEGF activity by blockade of V EGF receptor‐2 (R‐2) function prevents angiogenesis and decreases tumor growth in colon carcinoma liver metastases.
Abstract: BACKGROUND
Recent studies have suggested that vascular endothelial growth factor (VEGF), in addition to its proangiogenic properties, also functions as a survival factor for endothelial cells. The authors hypothesized that inhibition of VEGF activity by blockade of VEGF receptor-2 (R-2) function prevents angiogenesis and decreases tumor growth in colon carcinoma liver metastases.
METHODS
Spleens of mice were injected with human colon carcinoma cells producing liver metastases. After 7 days of tumor growth, groups of mice received either antibody to VEGFR-2 (DC101) or phosphate-buffered saline (control). In a follow-up experiment, a similar treatment regimen was followed except that mice were sacrificed at 1-week intervals to assess the time course of endothelial cell and tumor cell apoptosis.
RESULTS
After 21 days of therapy, the authors observed a significant decrease in vessel counts in liver metastases from human colon carcinoma in nude mice after therapy with VEGFR-2 antibody. Tumor cell apoptosis was increased significantly in the tumors of mice receiving DC101. Temporal studies with immunofluorescent double staining for the microvasculature and apoptotic cells revealed an increase in endothelial cell apoptosis that preceded an increase in tumor cell apoptosis. In vitro, treatment of human umbilical vein endothelial cells with antibody to VEGFR-2 produced a > 2.5-fold increase in endothelial cell apoptosis.
CONCLUSIONS
Therapy targeting the VEGFR-2 inhibited tumor growth in a murine model of colon carcinoma liver metastasis. Surprisingly, this therapy did not only inhibit angiogenesis but also led to endothelial cell death. These findings suggest that VEGF, via VEGFR-2 signaling, functions as a survival factor for tumor endothelial cells in liver metastases from colon carcinoma.

TL;DR: The evidence that nicotine and subtype selective nAChR ligands can provide neuroprotection in in vitro cell culture systems and in in vivo studies in animal models of neurodegenerative disorders is discussed.
Abstract: In the last five years there has been a rapid explosion of publications reporting that neuronal nicotinic acetylcholine receptors (nAChRs) play a role in neurodegenerative disorders. Furthermore, there is a well-established loss of nAChRs in post-mortem brains from patients with Alzheimer's disease, Parkinson's disease and a range of other disorders. In the present review we discuss the evidence that nicotine and subtype selective nAChR ligands can provide neuroprotection in in vitro cell culture systems and in in vivo studies in animal models of such disorders. Whilst in vitro data pertaining to a protective effect of nicotine against nigral neurotoxins like MPTP is less robust, most studies agree that nicotine is protective against glutamate and beta-amyloid toxicity in various culture systems. This effect appears to be mediated by alpha7 subtype nAChRs since the protection is blocked by alpha-bungarotoxin and is mimicked by alpha7 selective agonists. In vivo studies indicate that alpha7 receptors play a critical role in protection from cholinergic lesions and enhancing cognitive function. The exact subtype involved in the neuroprotectant effects seen in animal models of Parkinson's disease is not clear, but in general broad spectrum nAChR agonists appear to provide protection, while alpha4beta2 receptors appear to mediate symptomatic improvements. Evidence favouring a protectant effect of nicotine against acute degenerative conditions is less strong, though some protection has been observed with nicotine pre-treatment in global ischaemia models. A variety of cellular mechanisms ranging from the production of growth factors through to inactivation of toxins and antioxidant actions of nicotine have been proposed to underlie the nAChR-mediated neuroprotection in vitro and in vivo. In summary, although the lack of subtype selective ligands has hampered progress, it is clear that in the future neuronal nAChR agonists could provide functional improvements and slow or halt the progress of several crippling degenerative diseases.
